An autopsy case of a 65-year-old male who died of hepatocellular carcinoma superimposed on liver cirrhosis complicated with systemic sarcoidosis is presented. No organ metastasis of hepatocellular carcinoma was found except for a minute tumor embolus in the left upper lobe of the lung. Involved organs by sarcoidosis were the lymph nodes, lungs, heart, liver and spleen, but its presence was not noticed before death. Its cardiac involvement coincide with his clinical symptom of exertional dyspnea and the ECG finding of A-V block.

Twenty-four cases of hepatoblastoma, 14 cases of hepatocellular carcinoma and three cases of malignant mesenchymoma out of a total of 54 primary liver tumours were studied by light microscopy and immunohistochemistry. A remarkable finding in one case of hepatoblastoma and one case of hepatocellular carcinoma was a sarcoid-like reaction in the tumour tissue. Three cases of hepatoblastoma presented a macrotrabecular pattern. Among hepatocellular carcinomas, three cases corresponded to the fibrolamellar variant. By immunohistochemistry, the proportion of cases with positive staining for alpha 1-fetoprotein was higher in hepatoblastoma than in hepatocellular carcinoma. HBs-antigen could be demonstrated in non-neoplastic liver cells in two cases of hepatocellular carcinoma, but not in the tumour cells. No strong correlation between histological pattern and prognosis could be established in hepatoblastoma. However, there was a tendency to more aggressive biological behavior in cases with pronounced mitotic activity. The number of mitoses in hepatoblastoma varied widely. As in previous studies, patients with the fibrolamellar variant of hepatocellular carcinoma fared better than those with the classical type of this tumour. Prognosis in malignant mesenchymoma was not as poor as suggested from previous studies.

15 healthy subjects and 39 patients with focal liver and spleen lesions were examined via MR tomography at 1.5 tesla. Gradient field echos at small angle excitation (less than 90 degrees) were employed. The imaging time per layer was 10 seconds so that rapid imaging could be carried out at respiratory standstill. This enabled visualisation of liver and spleen without interference by breathing artifacts and with accurate localisation. Focal lesions can be imaged best at low flip-angle pulses (liver) or low to medium-angle pulses (spleen). The primary liver cell carcinoma is visualised as an inhomogeneous structure with similar signal intensity as the surrounding tissue. All other examined liver lesions (metastases, haemangiomas, lymphatic infiltrates, echinococcus cysts, FNH, gummae) showed greater signal intensity than the remaining organ at small angle excitation. Furthermore, contrast reversals were seen at medium-angle pulses. Contrariwise, with the exception of the light-coloured spleen infarcts, spleen lesions (lymphatic infiltrate, Boeck's disease or sarcoidosis) appeared darker at all excitation angles than the surrounding tissue.

The high incidence of hepatic lesions in sarcoidosis contrasts with the extreme rarity of portal hypertension. The mechanism of the latter is as obscure as the pathogeny of the disease. The liver may contain many or very few tuberculoid follicles, and its structure may be normal and non-fibrotic (as in our first two patients) or sclerotic, though rarely cirrhotic. In most cases the spleen is enormous, which raises the problem of portal hypertension by overload. Our third patient seems to be an unique case of progressive change to malignant hepatoma with osseous metaplasia, complicated with cervical metastases.

A case of primary hepatocellular carcinoma is described in a patient with long-standing sarcoidosis of the liver associated with chronic active hepatitis, and the MZ alpha-1-antitrypsin phenotype. This association appears to be unique. The respective roles of alpha-1-antitrypsin deficiency, sarcoidosis and chronic active hepatitis in the development of hepatocellular carcinoma in this case are uncertain.

A survey of all patients in whom liver biopsy showed epithelioid granulomas was undertaken at two major teaching hospitals in Glasgow for the period 1970-1979. Seventy-seven patients with hepatic granulomas were studied retrospectively. In 53 cases (69 per cent) a clear-cut clinical diagnosis was established, which included sarcoidosis (eight cases), tuberculosis (eight), extrahepatic biliary obstruction (seven), primary liver diseases (11), neoplasm (six), bacterial infection (five) and miscellaneous (eight). In 24 patients (31 percent) no cause was found. Seventeen patients from this idiopathic group were studied prospectively and single examples of the following conditions were subsequently diagnosed; pulmonary tuberculosis, primary biliary cirrhosis, ulcerative colitis, adenocarcinoma of rectum, primary hepatocellular carcinoma, alpha-one antitrypsin deficiency and pulmonary fibrosis, sarcoidosis, pulmonary fibrosis alone, gallstones, rheumatic heart disease, unexplained hepatosplenomegaly and one death from mesenteric artery thrombosis. Only six cases remained truly idiopathic. Three of these patients recovered and in two liver biopsy became normal. The other three have persistent granulomas associated with continuing illness.

Cross-sectional imaging is playing an increasing role in diagnosis of diffuse liver diseases because it clarifies, in many cases, the overlap in clinical and laboratory manifestations often present in diffuse hepatic processes and thus may eliminate the need for a biopsy. Advances in cross-sectional imaging, particularly in magnetic resonance (MR) imaging, enable further characterization of hepatic parenchymal and architectural changes, allowing closer correlation with underlying pathologic changes. Advanced imaging techniques can be used to characterize a variety of metabolic, vascular, toxic, infectious, and neoplastic diffuse liver diseases. These include more common entities such as cirrhosis, Budd-Chiari syndrome, hemochromatosis, Wilson disease, fatty change, and diffuse neoplastic disease (hepatocellular carcinoma, metastasis, and lymphoma) and uncommon entities such as schistosomiasis, sarcoidosis, and amyloidosis. Correlation of computed tomographic and MR imaging findings with underlying pathologic features is helpful in understanding the gamut of diffuse diseases of the liver.

Non-caseating epithelioid-cell granulomas named "sarcoid reactions" may occur rarely in regional lymph nodes of a malignant tumor. In this article, sarcoid reactions in a patient with hepatocellular carcinoma and two early gastric carcinomas are reported. A 78-year-old woman followed with a Hbs antigen positive liver cirrhosis from 1980 was admitted to our hospital to receive the operation for two early gastric carcinomas and hepatocellular carcinoma. Subsegmentectomy of the liver and subtotal gastrectomy were performed. Histologic examination of dissected lymph nodes revealed sarcoid reactions. There have been no reports regarding the association between sarcoid reactions and hepatocellular carcinoma combining early gastric carcinoma.

Neurocysticercosis (NCC), which is caused by infection with the larval stage of the pork tapeworm (Taenia solium), is now recognized as a major cause of neurologic diseases in countries where the infection is endemic. Migration of persons from these countries is resulting in diagnosis and local transmission in nonendemic countries at increasing rates. In the present study, immunoblotting and an ELISA were carried out using antigens of T. solium cysticerci fractionated by isoelectric focusing and serum samples from patients with NCC, alveolar (AE) or cystic echinococcosis (CE), and other diseases. Immunoblot analysis revealed antigens fractionated by isoelectric focusing (pH 9.2-9.6) either from cyst fluid of T. solium cysticerci or from intact cysts had unique components (glycoproteins) highly specific and sensitive for detection of NCC exclusively. All confirmed NCC serum samples (53 of 53) recognized at least three major bands of 10-26-kD of fractions with pH 9.2-9.6 from either intact cysts or cyst fluid. These bands were not recognized by sera from patients with other parasitic diseases including AE (0 of 34), CE (0 of 36), or other heterologous parasitoses (0 of 77), patients with hepatoma (0 of 19) or sarcoidosis (0 of 11), or sera from healthy controls (0 of 29). The ELISA using the antigens showed the same sensitivity and specificity for differentiation of NCC (53 of 53) from other diseases (0 of 107) or healthy individuals (0 of 29). Both immunoblotting and the ELISA using the fractionated antigens readily differentiated all NCC from AE or CE in a blind test of 29 serum samples of persons with NCC, CE, and AE. Antigens fractionated from cyst fluid of T. solium cysticerci by a simple, single-step isoelectric focusing (pH 9.2-9.6) are highly specific and sensitive for differential serodiagnosis of NCC in immunoblotting and/or an ELISA.
